Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flexible film,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a flexible display film fusing device, and more particularly, to a flexible display film fusing device, in which, when a film is stuck to a side surface of a glass having a non- The present invention relates to a flexible display film laminating apparatus.

The display device has been mainly limited to TVs and monitors in the past, but the development of technology has been rapidly shifting to a flat panel display (FDP: Flat Panel Display) which is easy, thin and light in weight.

Such a flat panel display (FDP) uses a plate type glass such as a liquid crystal display (LCD), a plasma display panel (PDP), an organic electroluminescence display (OLED) Flexible flexible displays, however, can be applied to a wide range of applications beyond the conventional flat display, and therefore the industry's interest and research on flexible displays with stable lines is increasing day by day. .

Since the flexible display device is flexible, it does not refer to only bending arbitrarily, but it does not bend, but the display surface itself includes various curves other than a straight line.

In the case of such a curved display, since the installation site can be more widely applied, a variety of devices having curved display are developed in a smart phone, thereby giving a new aesthetic feeling and functionality.

However, in the process of attaching the film to the flexible display having such a curved line, there is a disadvantage in that the defective rate such as generation of bubbles and the pressure of the glass in the adhesion process is increased, and unlike the flat surface, Is consumed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

FIG. 1 is a perspective view showing a film seating unit according to an embodiment of the present invention, FIG. 2 is a side view showing the operation of the film seating unit according to an embodiment of the present invention, and FIGS. A bottom plate 11 having a pair of vertical panels 111 vertically installed on both sides of the bottom panel 11 and a guide plate 11 fixed to the top surface of the bottom panel 11, A lower inclined block 12 mounted on the upper surface of the block 121 and having an inclined surface inclined upward in the front and moving in the forward and backward directions by the first transmission cylinder 122 and a lower inclined block 12 vertically formed on the vertical panel 111 The lower inclined block 12 is mounted on the bottom surface of the lower plate 132 of the flat plate type in combination with the pair of first guide rails 131 and has an inclined surface in close contact with the inclined surface of the lower inclined block 12, In accordance with the forward and backward movement of the And the upper end of the pressure regulating cylinder 141 mounted at the center of the upper surface of the lower table 132 is connected to the center of the bottom of the lower table 132 and the both ends of the pressure regulating cylinder 141 are connected to the first guide rail 131 The upper table 14 includes a pair of second guide rails 142 extending upward and downward and extending in the left and right direction. The second guide rails 142 are coupled to the lower surface of the second power transmission cylinder 151 A moving table 15 mounted on a rotating shaft 162 extending in the front-rear direction and rotating by a rotating motor 161 on the upper surface of the moving table 15, A pressure roller 164 mounted on the upper side of the pair of roll fixing brackets 163 and connected to the upper end of the pair of roll fixing brackets 163 and having a diameter larger than that of the pressure rollers 164 mounted on the roll fixing brackets 163, And a support roller 165 whose upper portion is closely adhered to the lower portion And a film pressing unit pressing the film unit 1 is configured including 16;

The glass fixing block 22 to which the opposite surface to which the film 200 of the glass 100 is to be mounted is tightly fixed is located at the vertical upper portion of the film pressing device 16 And a glass fixing part (2) for fixing the flexible display film.

The worker first fixes the glass 100 to the glass fixing block 22 and places the film 200 on the vertical lower portion of the glass fixing part 2 and the first electric cylinder 122 in the film mounting part 1, And the rotary motor 161 is positioned at one end of the pressure roller 164 where the glass 100 and the film 200 are joined together.

Thereafter, the moving table 15 moves along the second guide rail 142, and the pressing roller 164 advances the process of attaching the film 200. As shown in the figure, the glass 100 is curved The roll fixing bracket 163 can be adjusted so that the roll fixing bracket 163 can be positioned in the most effective direction for joining by using the rotation motor 161. [

The diameter of the pressing roller 164 is preferably smaller than that of the curved surface formed on the glass 100, and the outer surface of the pressing roller 164 is preferably made of a material having an elastic restoring force.

Further, in order to keep the pressure applied by the pressure roller 164 constant, the pressure regulating cylinder 141 relieves a high pressure in the lower portion and rises at a low pressure so that the film 200 is uniformly adhered and bonded, And the glass 100 is prevented from being damaged by an excessive force applied thereto.

Since the pressure roller 164 has a shape of a thin rod, it may be squeezed by pressure. Therefore, both ends of the pressure roller 16 are attached to the roll fixing bracket 163 of the film pressing unit 1 And a support roller 165 having a diameter larger than that of the pressure roller 164 and having an upper portion adhered to a lower portion of the pressure roller 164 is provided to prevent squeezing of the pressure roller 164.

When the supply of the film 200 in this embodiment is carried out while being unwound while being rolled by the roll from one side, the joining roller 164 performs a laminating operation from the far end of the cut film 200, It is possible to cut off the film 200 by a separate cutting device and then repeat the operation of feeding the film 200 again.

However, in this method, there is a need to further cut the film 200 because the film 200 is cut out of the edge of the glass 100 to which the adhesion has been completed. In this case, There is a fear that this may happen and the operation becomes complicated.

The present invention relates to a flat plate type film seating plate (hereinafter referred to as " flat plate type flat plate type flat plate type flat plate type flat plate type flat plate type " And a pair of film guide portions 3 having a mounting step 34 which is depressed at an upper edge of the film seating plate 33 in the direction of the film pressing portion 1 As shown in Fig.

The worker feeds the film 200 so that both ends of the film 200 are laid over the seating step 34 approaching each other by the fourth electric cylinder 31 and the film 200 is convex upward and the fifth electric cylinder 32 Lifts the film guide portion 3 so that the film 200 is positioned directly below the glass 100. [

The film pressing device 16 of the film seating part 1 is lifted and the pressing roller 164 comes to the position where the film 200 is pressed and attached to the glass 100. When the film is seated by the fourth electric cylinder 31 The operation of moving the plate 33 away from the plate 33 and lowering the plate 33 is repeated or automatically performed.
